| Keywords: Elihu Thomson's Tesla coil circuit Feb 1892 rotated.png Tesla coil circuit invented by Elihu Thomson and published in February 1892 The Tesla coil was a spark-excited resonant transformer circuit invented by Serbian American inventor Nikola Tesla and patented by him US patent 454 622 April 25 1891 which produced very high voltage high frequency current However many sources confirm that Tesla was not the first to invent this circuit Although this circuit was published a year after Tesla's invention Thomson claimed to have been experimenting with similar circuits in 1890 including one which could produce 60 inch sparks and many other sources confirm this This circuit essentially identical to Tesla's circuits of the time consists of A high voltage step-up transformer producing 15-20 kV b primary capacitor J spark gap with compressed air blowout to prevent it from arcing continuously C air-core resonant transformer consisting of a 15-20 turn helix of heavy wire surrounded by a glass cylinder on which are wound 150 turns of fine wire immersed in a tank of oil for insulation D output spark gap Thomson wrote that the output voltage was 150 000 volts but was limited only by the coil insulation Alteration to image rotated 90° CCW 1892-02-20 Retrieved November 21 2015 from https //books google com/books id JUtEAQAAIAAJ pg PA117 dq thomson Elihu Thomson Induction by high potential discharges in Electrical World magazine W J Johnson Co New York Vol 19 No 8 February 20 1892 p 117 fig 7 on Google Books Elihu Thomson Thomson died in 1937 other versions Elihu Thomson's Tesla coil circuit Feb 1892 png unrotated image PD-old-70-1923 Tesla coil circuits | ||||
